LIQUID OEMEI'NTING-PAINTL My" VGIltlOh relates t9 illiquid P adapted for. use ascements to join theseams of roofing and like material or for painting wflexible' coverin containing brtum'ens, pitches, or otheringredients of a plastic nature. a r

'The object of my invention ,is to roduce a ermanent weatherproof aint of t e above t will stick to the' indicated character, whic roofing or like foundation withqut cracking under the'influence of temperature changes or when the foundation is rolled. and unrolled and the ingredients of whieh will have no, injurious action uponeach other or upon -the foundation andwill not themselves be detrimentally affected by the foundation My improved saint com rises three ingredients-town, t, a be or binder; sec- 0nd,, a pigment," and, thir a more or less volatile so vent. I

I have found that in order to satis the re uirements of my invention the bin eror bo y should consist of a substance or a mixture of substances fulfillingthe following conditions: first periods. For practical purposes of course it is further requ red that the substances used should not be too expensive.

All pitches which comply with the requirements above indicated may be successfully emplo ed in the manufacture of my improve paints. -These pitches all possess the characteristic of being transparent,;translu- Specification of anai-irritant. Application and 11mm 31, 1905. Serial 11 .263.1441.

When employing metallic oxide as pigments, they 'shoul be used in anjextremelyfine state of subdivision, such as is obtained by air or water floating, thus dispensing with a grinding o I ration. It has been'found .tha-t'grindin e pigment-when mixed'with the binder an the so vent is not a satisfactory procedure on account of the loss of'solvent by evaporation $111511 the liability of the paint to gum up the As solvents mayem log various -substances, and I have found t e li hter fractions of petroleum, c'oal-tar,an wood-tar distillates particularly suitable for dissolvin the pitches of the'character above indicate Great care shouldfbeused to prevent the ge-' latinizationi For this purpose one should avoid the use of itches of animal or vegetable origin While have been distilled too far,'since they lack suflicient plast icity,'p ossess an extremely-dark color due to excessive 'carbonlzation, and are apt to gelati'nize after they have been dissolved. This gelatiniza v tion sometimes occurs immediately'after the cooling of the solution, but may even take jpl ace after the solution has been kept -for sometime, not of a tough rubber-like consistency will permanently remain in the form of a hmpid 'Thenature of the solvent em- Medium and soft pitches when solution. 7 ployed likewise influences the behavior of the solution to some extent, and gelatinization is less aptjto occurwith the use ofcoal-tar distillates than with petroleum products.

The binder or body should of course not be too dark,v since otherwise it will mask the pigment, whereas the object of my invention is Iprovide a body the color .of which will be" i to ob terated or at'least dominated by that of the pigment v T e process of manufacturing the paint is extremelysimple, and consists in first dissolving the pitch in one of the stated solvents by signed for cementing the seams of co I liberal coat will last several years, and al- 2 5" zation, although a preponderance of such substance won though a slight oxidation will occur, particu larly when first exposed to the weather, it will remain plastic and be unaflected by thegcom tinual expansion and contraction of the foun-- dation. In this respect it differs from all" other paints.

The addition of materials other' tl ian those mentioned is permissible, provided the lasticity and weather-resisting qualities 0 the coating are-not affected. Thus the use of a; small percentage of 'a resinous substance may serve to bring-out the color of the pigmentswith greater intensity and preventgelatinid prove hi hly injurious to the coating. I may. also a d a dark. pitch to the body or binder herein described, provided the percentage of such addition is not high enough to mask the color of the pigmerit.
